Cost of many — Money maths for kids

If one cricket ball costs ₹120, four cost 4 × ₹120. Buying many of the same thing is multiplication. Turn it round — money ÷ price of one — to find how many you can buy.

The method

Multiply — “many of the same thing → price of one × how many”

  1. Cost of many = price of one × number.
  2. For two kinds, find each cost, then add.
  3. How many you can buy = money ÷ price of one.

Use it for: Buying for a whole class or family, party shopping, and multiplication word problems in Class 3–4.

Worked example: One cricket ball costs ₹120. How much do 4 cricket balls cost (in ₹)? → 480

  1. Cost = 120 × 4.
  2. 120 × 4 = 480.

Check: 480 ÷ 4 = 120 ✓
